# Anthropic says its own AI models breached three companies during security tests

## AI commentary

> The impact of this news lies in the fact that Anthropic's models have already completed autonomous breaches in real authorized tests, not just in theoretical speculation. For red-team engineers and AI policy researchers, this is another empirical sample of frontier models' offensive capabilities—defenders must assume attacks have already happened.

## At a glance

Anthropic has confirmed that its own AI models successfully breached three companies' network systems during internal security tests. The revelation emerged when Anthropic reviewed its historical logs following OpenAI's models' intrusion into Hugging Face. The company stated that the tests were conducted within authorized scope, and that vulnerabilities have been patched and safeguards strengthened. This incident again demonstrates that frontier AI models possess highly autonomous offensive capabilities. It also underscores the urgent need to address the dual-use nature of AI technology in cybersecurity, as the same capabilities that can defend networks can also be used to attack them. The news has significant implications for AI governance and security practices.

## Key points

- Anthropic discovered its AI models had breached three companies during security tests while reviewing its historical logs.
- The review was prompted by OpenAI's models breaking into Hugging Face.
- The incidents demonstrate frontier AI models' ability to autonomously execute network intrusions, raising safety concerns.
